A nurse is caring for a client who has liver cirrhosis with ascites, bleeding esophageal varices, and portal hypertension. The nurse recognizes which of the following laboratory findings as indicating the client's gastrointestinal (GI) tract is digesting and absorbing blood?

Decreased bilirubin

Decreased chloride

Elevated blood urea nitrogen (BUN)

Elevated HbA1c

Answer and Explanation

The Correct Answer is C

Rationale:
A. Decreased bilirubin is unrelated to digestion of blood in the GI tract.
B. Chloride levels do not indicate blood digestion.
C. When a client with esophageal varices bleeds into the GI tract, the digestion and absorption of blood proteins lead to increased nitrogen load, reflected as elevated BUN.
D. HbA1c reflects long-term blood glucose control, not acute digestion of blood.

Correct Answer is D

Explanation

Rationale:
A. Percutaneous Transhepatic Cholangiography (PTC) involves inserting a needle through the skin into the liver to visualize bile ducts, not using endoscopy.
B. Endoscopic Ultrasound (EUS) uses an endoscope with ultrasound to image structures near the GI tract but does not combine with radiographic imaging of the ducts.
C. Magnetic Resonance Cholangiopancreatography (MRCP) uses MRI to noninvasively visualize bile and pancreatic ducts, without endoscopy.
D. Endoscopic Retrograde Cholangiopancreatography (ERCP) combines endoscopy with radiographic imaging to examine the bile and pancreatic ducts, allowing both diagnosis and therapeutic interventions.

A. Obtain a dietary history from the client. B. Review the client's electrolyte values. C. Investigate the client's emotional concerns. D. Check the client's perianal skin integrity.

Correct Answer is B

Explanation

Rationale:
A. Obtaining a dietary history is important but not the priority in an acute exacerbation.
B. Reviewing electrolyte values is the first action. Clients with acute ulcerative colitis are at risk for fluid and electrolyte imbalances due to diarrhea, making this a priority assessment to prevent complications.
C. Investigating emotional concerns is important for holistic care but is secondary to addressing physiologic needs.
D. Checking perianal skin integrity is necessary but comes after assessing critical physiologic risks like electrolyte imbalances.
